Thousands of sequences that control genes are active in the developing human limb and may have driven the evolution of the human hand and foot, a comparative genomics study led by Yale School of Medicine researchers has found

In nearly every organism's genome, scattered between genes that encode proteins, long regulatory regions stretch across expanses of DNA. Understanding what role these so-called enhancer regions play in controlling the activation ...

(Phys.org) —Honey bees don't start out knowing how to find flowers or even how to get around outside the hive. Before they can forage, they must learn how to navigate a changing landscape and orient themselves in relation ...

University of Montreal researchers have discovered a novel molecular mechanism that can potentially slow the progression of some cancers and other diseases of abnormal growth. In the May 23 edition of the prestigious journal ...

The normal development of an animal or plant can be compared in at least two ways with the successful performance of a great symphony. The whole is the product of a great number of events involving contributions by many different ...

During embryo development, genes are dynamically, and very precisely, switched on and off to confer different properties to different cells and build a well-proportioned and healthy animal. Fgf8 is one of the key genes in ...

Over the past several years, Rong Li, Ph.D., at the Stowers Institute for Medical Research has been making crucial discoveries about the development of cell polarity—the process by which one side of a cell becomes different ...

When animals and plants are exposed to influences such as bacterial attack, odour and cold, calcium ions flow into the cells. The calcium provides the cells with a signal about what is going on outside, but as high concentrations ...

A research group at Aarhus University has gained unique insight into how bacteria control the amount of toxin in their cells. The new findings can eventually lead to the development of novel forms of treatment for bacterial ...
